Hi,
I'm facing the problem that gpsd v3.20 ignores the Galileo satellites. My gpsd clients only see max 20 satellites, while on the smartphone I see above 30.
I'm using a Quectel LC79D GNSS emitting NMEA0183. I have confirmed it has all constellations enabled in its settings.
It sends the GAGSV sentences, when I read the serial port directly:

However, the Galileo satellites are missing from the "SKY" structure in JSON output of GPSD. xpgs and cgps don't show these satellites. When running gpsd with debug info, it shows
psd:INFO: Sats used (16):
gpsd:IO: <= GPS: $GAGSV,2,1,03,102,86,060,30,103,,,12,6*4B

gpsd:PROG: GAGSV is just after a cycle ender.
This log is emitted by NMEA parser:
https://gitlab.com/gpsd/gpsd/-/blob/master/drivers/driver_nmea0183.c#L3727I'm not familiar with GPSD codebase. Is the cycle ender printout a problem at all?
I gathered more debug info with

Do you know how to fix this situation?
